Quasi-periodic flux variations in pulsar 1A 0535+262 are accompanied by synchronized cyclotron line energy oscillations, providing evidence for rapid geometric reconfiguration of the accretion column in the radiation-pressure-dominated regime.

Phase-resolved high-resolution spectroscopy of M82 X-2 with XRISM Resolve finds broader Fe Kα line during pulse peak, indicating origin in the accretion flow with velocity dispersion of about 1700 km/s.
First detection of mHz QPOs in 1A 0535+262 below 27 keV with frequencies evolving from 41 to 93 mHz, mostly hard lags, and double-peaked high-energy structure near outburst peak, interpreted as linked to soft-photon source and Comptonizing outflow evolution.
X-ray timing and spectral analysis of ASKAP J174508.9-505149 detects matching periodicity and features consistent with an accreting magnetic CV.
Numerical solutions of hydrodynamics and polarized radiative transfer show that resonant Compton scattering near the cyclotron resonance redistributes radiation and reduces light-curve modulation amplitude in subcritical X-ray pulsars.
A new relativistic model for accretion-powered X-ray pulsars enables simultaneous computation of phase-averaged spectra and pulse profiles, applied to NuSTAR data for Her X-1 to extract physical parameters and beaming patterns.
New XRISM observations confirm a highly broadened, pulsating Fe K line from the accretion column of Hercules X-1 that varies with pulse phase and evolves with the 35-day precession cycle.
The 2026 outburst of 1A 1118-61 is brighter and spectrally harder than in 2009, with constant cyclotron line energy across large luminosity changes and QPO frequency suggesting magnetospheric instabilities.
Radiation-hydrodynamic simulations of subcritical X-ray pulsars find resonant Compton scattering governs plasma deceleration, vacuum polarization dominates birefringence to enhance cyclotron features, and cyclotron energy rises with accretion luminosity.
